SUPPLEMENTARY INFORMATION:
Background
Citrus greening, also known as huanglongbing disease of citrus, is
considered to be one of the most serious citrus diseases in the world.
Citrus greening is a bacterial disease caused by strains of the
bacterial pathogen ``Candidatus Liberibacter asiaticus'' that attacks
the vascular system of host plants. The bacteria are phloem-limited,
inhabiting the food-conducting tissue of the host plant, and causes
yellow shoots, blotchy mottling and chlorosis, reduced foliage, and tip
dieback of citrus plants. Citrus greening greatly reduces production,
destroys the economic value of the fruit, and can kill trees. Once a
tree is infected with citrus greening, there is no cure for the
disease. In areas of the world where citrus greening is endemic, citrus
trees decline and die within a few years and may never produce usable
fruit. Citrus greening was first detected in the United States in
Miami-Dade County, FL, in 2005, and is only known to be present in the
United States in the States of Florida and Georgia, two parishes in
Louisiana, and two counties in South Carolina.
The bacterial pathogen causing citrus greening can be transmitted
by grafting, and under laboratory conditions, by dodder. There also is
some evidence that seed transmission may occur. The pathogen can also
be transmitted by two insect vectors in the family Psyllidae:
Diaphorina citri Kuwayama, the Asian citrus psyllid (ACP), and Trioza
erytreae (del Guercio), the African citrus psyllid. ACP can also cause
economic damage to citrus in groves and nurseries by direct feeding.
Both adults and nymphs feed on young foliage, depleting the sap and
causing galling or curling of leaves. High populations feeding on a
citrus shoot can kill the growing tip. ACP is currently present in
Alabama, California, Florida, Georgia, Guam, Hawaii, Louisiana,
Mississippi, Puerto Rico, South Carolina, and Texas. Based on regular
surveys of domestic commercial citrus-producing areas, the African
citrus psyllid is not present in the United States.
The Animal and Plant Health Inspection Service (APHIS) of the
United States Department of Agriculture (USDA) has undertaken measures
to control the artificial spread of citrus greening to noninfested
areas of the United States since its introduction in 2005. On September
16, 2005, APHIS issued a Federal Order designating one affected county
in Florida as a quarantined area, and imposing restrictions on the
interstate movement all citrus greening and ACP host material from this
area.\1\

Federal order referenced in this document, go to http://www.aphis.usda.gov/plant_health/plant_pest_info/citrus_greening/regs.shtml.
---------------------------------------------------------------------------
In January 2006, we issued an environmental assessment titled
``Citrus Greening Control Program in Florida Nurseries'' (January
2006).\2\ This document assessed the environmental impacts associated
with the use of the pesticide treatments acetamiprid, chlorpyrifos,
fenpropathrin, imidacloprid, kaolin, and a cyfluthrin/imidacloprid
mixture as part of a disease control program for citrus greening and
ACP.

---------------------------------------------------------------------------
On November 2, 2007, we issued a revised order that designated
additional counties in Florida as areas quarantined for citrus
greening, and that quarantined 32 counties in Texas, the entire States
of Florida and Hawaii, the entire Territory of Guam, and the entire
Commonwealth of Puerto Rico for ACP. The November 2007 order also
contained treatments that could be performed on ACP regulated articles
to allow their movement from a quarantined area to areas of the United
States other than commercial citrus-producing States. The order stated
that, prior to movement, host material (other than Bergera (Murraya)
koenigii, or curryleaf) had to be treated using an Environmental
Protection Agency-approved product labeled for use in nurseries. The
articles had to subsequently be treated with a drench containing
imidacloprid as the active ingredient within 30 days prior to movement
and with a foliar spray with a product containing acetamiprid,
chlorpyrifos, or fenpropathrin as the active ingredient within 10 days
prior to movement. Provided that it did not originate from an area
quarantined for citrus greening, curryleaf could be moved interstate to
any State following treatment with methyl bromide according to the
APHIS-approved treatment schedule MB T101-n-2, found in 7 CFR part 305.
We accompanied this revised order with a notice \3\ published in
the Federal Register on November 2, 2007 (72 FR 62204-62205; Docket No.
APHIS-2007-0135), in which we announced to the public the availability
of an environmental assessment titled ``Movement of Regulated Articles
from Citrus Greening and Asian Citrus Psyllid Quarantine Zones''
(October 2007). The assessment evaluated the possible environmental
impacts associated with implementation of the revised Federal Order,
and, in particular, the treatment schedules specified within it.

Since issuance of these documents, we have issued six additional
Federal Orders to designate new areas as quarantined areas for citrus
greening or ACP. In these orders, we have added irradiation treatment
at 400 gray as an approved treatment for ACP host articles, provided
that the articles do not originate from an area that is quarantined for
citrus greening. The latest Federal Order was issued on July 29, 2009.
Concurrent with the issuance of these Federal Orders, we have also
received requests from citrus industry representatives and State plant
health officials in several States with
[[Page 46411]]
commercial citrus production to examine the efficacy of in-ground
granular applications containing dinotefuran and foliar sprays
containing bifenthrin, deltamethrin, dinotefuran, or a mixture of
imidacloprid and cyfluthrin as pesticide treatments for ACP. We have
found them to be effective in treating regulated nursery stock for ACP.
Accordingly, we have completed an assessment of the environmental
impacts anticipated from a control program that would incorporate the
provisions of the latest Federal order, the use of these new granular
applications and foliar sprays as treatments for ACP, and additional
measures that are currently not included in the July 29, 2009 Federal
Order but that we consider necessary to prevent the spread of citrus
greening and ACP to currently unaffected areas of the United States.
APHIS' review and analysis of these potential environmental impacts
are documented in detail in an environmental assessment titled
``Quarantine and Interstate Movement of Citrus Greening and Asian
Citrus Psyllid'' (July 2009). We are making this assessment available
to the public for review and comment. We will consider all comments
that we receive on or before the date listed under the heading DATES at
the beginning of this notice.
The environmental assessment may be viewed on the Regulations.gov
Web site or in our reading room (see ADDRESSES above for instructions
for accessing the document on Regulations.gov and information on the
location and hours of the reading room). You may request paper copies
of the environmental assessment by calling or writing to the person
listed under FOR FURTHER INFORMATION CONTACT. Please refer to title of
the assessment when requesting copies.
The environmental assessment has been prepared in accordance with:
(1) The National Environmental Policy Act of 1969 (NEPA), as amended
(42 U.S.C. 4321 et seq.), (2) regulations of the Council on
Environmental Quality for implementing the procedural provisions of
NEPA (40 CFR parts 1500-1508), (3) USDA regulations implementing NEPA
(7 CFR part 1b), and (4) APHIS' NEPA Implementing Procedures (7 CFR
part 372).
Done in Washington, DC, this 2nd day of September 2009.

Acting Administrator, Animal and Plant Health Inspection Service.
